PAPER-CUTTING TOOL.

SPECIFICATION forming part of Letters Patent No. 533,374, dated January29, 1 895, Application filed December 14,1894. Serial No. 531,829- (Nomodel.)

To all whom it may concern:

Be it known that 1, CHARLES T. RIDGELY, a citizen of the United States,residing at Springfield, in the county of Clark and State of Ohio, haveinvented certain new and useful Improvements in PapenOutting Tools, ofwhich the following is a specification, reference being had therein tothe accompanying drawings.

This invention relates to certain new and useful improvements in toolsfor cutting paper, trimming window shades, cloth and such like, and suchimprovements consist in combining together a head which carries thecutting blade and a gage which travels on a guide strip and guides thedirection of the head with its blade, there being a pivotal connectionbetween the head and gage and a spring arranged near or about the pivotand acting to normallysupport the blade above the material to be out,but to permit it to be readily depressed down to the material.

In the accompanying drawings, 011 which like reference letters indicatecorresponding parts, Figure 1, represents a side elevation of myimproved tool complete, with a part in section, and an elevation of theguide strip with the tool applied thereto; Fig. 2, an end elevationthereof; Fig. 3, a sectional view on the line a: a: of Fig. 1, lookingdownward; Fig. 4., a detail perspective view of portions of the gagehead and blade, showing the arrangement of the pivot and spring; andFig. 5, aview looking at the reverse side of Fig. 1.

The letter A designates a guide strip of wood, with a'plate B on theupper side which overhangs the wooden partat one edge and thereby formsa way with which engages the gage. The adjoining edge of the guide stripisfaced off with a plate 0, the plates B and 0 being of metal,preferably of steel. They are secured to the stripA in any desiredmanner, as by means of screws D whose heads are flush with the surfacesof the plates.

At E is designated that part of the device which I term the gage. It isconstructed of cast metal, as iron or brass, and is provided along itslower edge with a groove F which receives the overhanging edge of theplate B, so that the gage will readily interlock with the plate Whilebeing free to slide back and forth thereon. This gage is hollowed out onthe inside to reduce its weight and to accommodate the head of the arboron which the blade is mounted. At one end the gage has screwed orotherwise secured to it a pivot device G, and at the other end itcarries a guide piece H held by a screw I and embracing the outer edgeof the head to guide the latter and hold it against the gage. A stop pinJ carried by the head comes in contact with this guide piece and limitsthe movement of the head in an upward direction. This head is designatedas K and is pivoted upon the pivot device G and is recessed as shown atL to retlon shown in Fig. 1, but readily yields when the head isdepressed so as to bring the cutter 0 down upon the paper or othermaterial to be out, which is held under the guide strip ,A. This bladeis in the form of a disk and is mounted to rotate on the arbor P whichis screwed into the head and held by a thumb jam nut Q. The head ishollowed out on the inner side to lighten it. It is also pro-' videdwith a thumb or finger place R and a handle S so as to be forciblydepressed against the material to be out. In using the tool it is slidalong the guide strip and is guided by it through the engagement of thegage therewith. The location of the pivot pin well to one side of theblade center and the location of the handle and thumb or finger placeatthe other side of the blade center, constitute a sort of lever of thehead, enabling the blade to be depressed with great force so that itwill go through many thicknesses of material, while the pivotalconnection of the head and gage renders the tool devoid of any bindingof the parts and While the spring yields to the depression of the head,but readily lifts the blade when the act of cutting is finished, so thatthe tool can be slid back on the gage and yet the blade be always abovethe table or material.

The broad feature of the pivoted head and gage and the spring and stopare the subject of claimsin my application, Serial No. 520,519, filedAugust 16,1894, for improvements in cutting tools, and are therefore notmade the subject of claims herein. 1

AS shown the guide piece 11 is attached to the gage, and the stop pin .Iis attached to the head, but it is obvious that either member may carrythe guide piece and either the stop.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In a cutting tool, the combination with the gage, of a head fittedthereto, a blade carried by the head, a pivotal connection connectingthe head and gage together, a spring near the pivot of said connectionand engaging with the head and gage, and a stop to limit the movementbetween the parts.

2. In a cutting tool, the combination with a gage, of a head fittedthereto, a blade carried by the head, a pivotal connection conmeetingthe head and the gage together, a

spring encircling the pivot of said connection 20 and engaging at itsends with the gage and head, a stop carried by the head and a guidepiece carried by the gage embracing the head and adapted to arrest saidstop.

3. In a cutting tool, the combination with the head having a recess, aspring fitted within the recess and engaging with the head, a gage, apivot connecting the gage and head together, and said spring alsoengaging with said gage.

In testimony whereof I affix my signature in presence of two witnesses.

CHARLES T. RIDGELY.
